By and large the Humane Society is an outstanding organization, a civic treasure that does so much good for so many people and animals. But that's all the more reason for it to reach out, not only to the public but to other groups and individuals equally committed to doing good works.
An issue such as the Maddie's Fund grant proposal raises legitimate arguments over how to handle animal overpopulation, and it should never be implied that agencies such as the Humane Society, which perform euthanasia, are the bad guys merely because they put animals to sleep. There's no doubt that they do things properly and humanely.
But can they say the same for how they treat others in the animal-protective community?
